Abstract. Starting from the Shannon channel capacity, we propose an IRUWB channel capacity based on the delay spread for multipath time variant channels. This IR-UWB channel capaci...

—The frequency hopping (FH) based ultra-wideband (UWB) communication system divides its available frequency spectrum into several sub-bands, which leads to inherent disparities b...
